In-patient is not BS.
You are not a loser; however, from what I've read and your own admission, you are an alcoholic who struggles with a medical diagnosis of schizophrenia (unsure of the gambling part).
I hear/read mania in your post which is troubling. The high and denial before the crash. I hope I'm wrong.
I wouldn't shut the door on any and all options for permanent recovery including in-patient and close contact with medical professionals.
Congratulations on your three weeks but please be mindful of your moods, patterns, and medication/therapeutic needs. Also, I really think remaining open to the possibility of an in-patient setting would strengthen your chances for a long lasting recovery.
